[0025] like Figures 1 to 7 As shown, the utility model provides a vehicle lamp structure with a modular light guide plate, a small light guide plate is arranged between the thick-walled part 2 and the rear shell 3 of the lamp, and a plurality of the small light guide plates are arranged in sequence along the length direction of the thick-walled part 2, that is, a plurality of the small light guide plates are combined into a light guide plate group corresponding to the length of the thick-walled part 2 to illuminate the entire thick-walled part 2, and the small light guide plate is fixed on the rear shell 3 of the lamp through the ear 11; compared with the existing technical solutions that require the design of light guide plate molds of different lengths to meet the needs of thick-walled parts 2 of different length models, the present application adopts a combination arrangement of a plurality of small light guide plates in the length direction to illuminate the thick-walled part 2, so that during production, only the mold corresponding to the small light guide plate needs to be used, and the number of small light guide plates can be increased or decreased according to the length of the thick-walled part 2 during assembly.

[0026] Specifically, the small light guide plate also includes a light guide portion 12 uprightly arranged relative to the thick-walled member 2, and the ear portions 11 are constructed on both vertical ends of the light guide portion 12; such a design allows the thick-walled members 2 to fit tightly when arranged in the length direction, thereby avoiding light leakage between adjacent thick-walled members 2; and now, because there are multiple small light guide plates, the problem of light crosstalk between each other can be greatly reduced, so that an RGB color change effect can be achieved, which is similar to the rhythmic effect of a music fountain.

[0027] Specifically, a transverse connecting portion 13 is constructed between the ear portion 11 and the light guiding portion 12. The LED light source is arranged facing the transverse connecting portion 13 and is located in the enclosed area of ​​the ear portion 11 and the transverse connecting portion 13, so that the LED light source first lights up the transverse connecting portion 13, and then lights up the gaps between adjacent small light guide plates and the light guiding portion 12 through the transverse connecting portion 13, so that the entire light guide plate group is evenly lit.

[0028] Specifically, a protruding shaping portion 21 is constructed on the end face of the thick-walled component 2 facing away from the small light guide plate. The shaping portion 21 is a three-dimensional shaping pattern designed to meet consumer needs. The decorative panel 4 is connected to the thick-walled component 2 by a sleeve, and a slot matched with the shaping portion 21 is provided on the decorative panel 4. The shaping portion 21 is connected by the sleeve of the decorative panel 4, so that other parts of the thick-walled component 2 except the shaping portion 21 are blocked, and thus when observing the car lights, the contrast effect of the luminous shaping portion 21 is more obvious.

[0029] Specifically, the lamp rear shell 3 is constructed with an inner concave threaded platform 31 corresponding to the ear portion 11 , and a fastening screw is passed through the fixing ear hole on the ear portion 11 and then threadedly connected to the inner concave threaded platform 31 , thereby achieving fixation of the small light guide plate.

[0030] Specifically, the vehicle lamp structure also includes a headlight cover 5, which is snap-fitted to the lamp rear shell 3; during assembly, after the small light guide plate is fixed to the lamp rear shell 3, the thick-walled component 2 connected with the decorative panel 4 is placed on the light guide plate group composed of a number of the small light guide plates, and then the headlight cover 5 is snap-fitted to the lamp rear shell 3, and the thick-walled component 2 and the decorative panel 4 are pressed tightly by the headlight cover 5.

[0031] The working principle and working process of the utility model are as follows:

[0032] When the LED light source is turned on, the LED light source first lights up the transverse connecting part 13, and then lights up the gaps between adjacent small light guide plates and the light guide part 12 through the transverse connecting part 13, so that the light guide plate group composed of several small light guide plates is all lit up. Since the length of the light guide plate group corresponds to the length of the thick-walled part 2, the entire thick-walled part 2 is lit, and the decorative plate 4 blocks the other parts of the thick-walled part 2 except the shaping part 21, so that when observing the car lights, the contrast effect of the luminous shaping part 21 of the thick-walled part 2 is more obvious.

[0033] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
